Y., assignor to Burndy Engineering Company,Inc., a corporation of New York Application January 4, 1945, Serial No.571,227

My invention relates to electric terminal connections and moreparticularly to a terminal for attachment to a terminal board to whichelectrical connections are made.

The objects of my invention are to provide a terminal which occupiesrelatively small space, to which electrical connections may be quicklymade, and which can be quickly and permanently attached to a terminalboard.

I accomplish these and other objects and obtain my new results as willbe apparent from the device described in the following specification,particularly pointed out in the claims, and illustrated in theaccompanying drawing in which:

Fig. l is a longitudinal cross-sectional View of my device.

Fig. 2 is a side-View illustrating the method of installations.

Fig. 3 is a similar view of my device attached to a terminal board.

Fig. 4 is a side-view partly in section of a modification of my device.

Fig. 5 is a side-view of another modification.

Fig. 6 is a side-View of a completed connection.

Referring more particularly to the drawing reference numeral ldesignates a tubular sleeve of metal having an eyelet ll secured theretoby soldering or brazing at the junction l2. The eyelet may be secured tothe sleeve at a point sufiicient to allow the upper and lower sectionsof the sleeve to have ample length for securing a conductor thereto.

The eyelet II contains the usual shoulder l3, and free edge It forrolling the edge into a clamping shoulder as shown in Fig. 2, by meansof a tool, hereinafter described.

For attachment to a Wall section, the tubular sleeve and integral eyeletis passed through an aperture E in the wall [6, as shown in Fig. 2. Aneyelet supporting tool l1, having a bore I8 is inserted over the freeend of the sleeve supporting the shoulder E3 of the eyelet.

A rolling tool- I 9 similarly provided with a bore 26 is inserted overthe remaining end of the sleeve Hi. The rolling edge 2i of the tool isshaped so as to force the free edge IA of the eyelet to roll over andsecure the eyelet with attached sleeve securely to the wall section I6.

The final result is illustrated in Fig. 3, wherein the sleeve andattached eyelet are fully secured 3 Claims. (Cl. 248-56) 2 to the wallsection [6, with the tool I1 and I9 Withdrawn.

One end of the sleeve may be formed into a terminal lug 25, as shown inFig. 4, provided with a central aperture 26, or the sleeve may beprovided with slots 30, shown in Fig. 5, for providing resilient prongs3| for resiliently engaging a pinjack, not shown.

Various methods may be used to secure a conductor to the sleeve. In Fig.6, a familiar type of indentation 40 is employed which forces the metalof the sleeve with tight engagement into the inserted conductor 4l'.

In the foregoing I have provided a construction for accomplishing, theobjects of my invention. The connection is compact, inexpensive to makeand install, contains fewer parts than are usually found, and provides asound connection for various electrical installations.

I have thus described my invention, but I desire it understood that itis not confined to the particular forms or uses shown and described, thesame being merely illustrative, and that the invention may be carriedout in other ways without departing from the spirit of my invention,and, therefore, I claim broadly the right to employ all equivalentinstrumentalities coming within the scope of the appended claims, and bymeans of which, objects of my invention are attained and new resultsaccomplished, as it is obvious that the particular embodiments hereinshown and. described are only some of the many that can be employed toattain these objects and accomplish these results.

I claim:

1. A connector for attachment to an apertured wall section comprising abody section having a cylindrical portion, a shoulder extendingcircumferentially about the cylindrical portion, and a circumferentiallyextending portion in non-movable relationship to the cylindrical portionhaving a diameter sufficient to enable the connector to be fitted intoan aperture of a wall section as a unit and being bendable to permit itto be forced in a plane transversely to the longitudinal axis of thecylindrical portion for supporting the cylindrical portion rigidly inposition on the wall section.

2. The connector of claim 1, wherein the shoulder and. thecircumferentially extending portion comprise an eyelet which is madeintegral with the cylindrical portion.

3. A connector for attachment to an apertured wall section comprising abody section having a cylindrical portion, a shoulder section extendingoircumferentially about the cylindrical portion, and a circumferentiallyextending portion having a diameter sufiicient to enable the connectorto be fitted into an aperture of a Wall section and being bendable topermit it to be forced in a plane transversely to the longitudinal axisof the cylindrical :portion for supporting the cylindrical portion -.inposition on the Wall section, said shoulder section andcircumferentially extending portion permanently being mounted to thecylin- 15 drical portion to form a unitary assembly before insertioninto the aperture of the wall section.
